Out timing circuit is highly reliable and, by design, virtually unaffected by temperature, EMI and other electrical disturbances. Series A Plus pumps continue to meet their specifications for pressure and capacity even during extended use. That's because of our high quality solenoid and special enclosure that effectively dissipates heat. Agency Approved and water resistant for demanding outdoor and indoor applications.
